Answer:
The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.
Explanation:
False, Some plasmids may reanneal without taking in any more DNA. when plasmid and foreign DNA are combined after being cut with the same restriction enzyme
Enzymes that cleave DNA are known as restriction enzymes. Each enzyme distinguishes one or more target sequences and cleaves DNA at or close to those sequences.
Numerous restriction enzymes produce single-stranded DNA overhangs at the ends of their cuts, which are often staggered. But some result in blunt endings.
DNA ligase is an enzyme that joins DNA. A single, unbroken DNA molecule can be created by joining two sections of DNA that have matching ends using ligase.
DNA ligase and restriction enzymes are employed in DNA cloning to splice genes and other DNA fragments into plasmids.
An enzyme that cuts DNA and recognises particular DNA locations is known as a restriction enzyme. A number of restriction enzymes make staggered cuts at or near their recognition sites to create ends with a single-stranded overhang.

Competition help to regulate population growth since only those who are able to obtain food survive.
Crop plants and weeds may compete for water and for sunlight.
Farmers spray herbicides early in the growing season to avoid competition between crop plants and weeds.
<h3>What is the effect of competition on population?</h3>
Competition among species help to regulate population growth by ensuring that only those who are able to obtain food survive. Thus, only fit individuals of a species survive.
Crop plants and weeds may compete for water because water enables them to carry out metabolic activities of growth and development.
Crop plants and weeds may also compete for sunlight and they need sunlight to carry out photosynthesis.
Farmers spray herbicides early in the growing season in order to avoid or reduce competition between crop plants and weeds.
In conclusion, competition among species helps to control overpopulation.

Answer:
c The trees will grow and the forest will be restored to its original form.
Explanation:
The ashes from the old trees will serve as nutrient for the new plants. its restores back the ecosystem because the old tress and ashes will decay which will return nutrient to the soil.
the new seedlings will be exposed to fresh air and sunlight which improve there germination.
